Patent DE-3443428-A1 (DE)
Title: Arrangement for supplying loads or load groups with an approximately constant frequency from a ship on-board power supply with a variable frequency
Inventor: DROSTE WERNER PROF DR ING
IPC: H02J3/34
Filed: 1984-11-29
Abstract: Synchronous shaft generators, which are driven via transmissions having a fixed transmission ratio from the propeller shaft, are used in order to supply the electrical on-board power supplies of ships economically. When the ship is travelling at a relatively slow speed, the rotation speed of the propeller shaft is less than the rated rotation speed, and in consequence the frequency of the on-board power supply is also less than the rated frequency. Many of the loads which are connected to the on-board power supply are insensitive to this drop in frequency, provided the power supply voltage is reduced in proportion to the frequency. However, a minority of the loads require an approximately constant frequency and voltage. In order to supply a portion of the power system to which these loads are connected, a converter is proposed which consists essentially of a rotary rotating-field machine. The rotating-field winding of the stator (or of the rotor) is connected to the power system having a variable frequency and voltage, and the rotating-field winding of the rotor (or of the stator) supplies the portion of the power system having an approximately constant frequency and voltage. The rotor is rotated by means of an auxiliary drive motor at such a rotation speed that the sum of the rotation frequency of the rotating field supplied from the power system having a variable frequency and the frequency of the rotor rotation is approximately constant.
Patent DE-3447073-A1 (DE)
Title: Liquefied-gas tank
Inventor: BACKHAUS HERBERT DR ING
IPC: B65D90/22
Filed: 1984-12-22
Abstract: The tank vessel (10) is connected to a water source (18) via an inlet valve (12). In the event of fire, the inlet valve (12) opens so that water flows into the lower area of the tank vessel (10) and cools the tank vessel (10) and raises its contents out of the fire zone. The water on which the liquefied gas floats can be discharged again in special cases by an outlet valve (13) arranged in the lower area of the tank vessel. Finally, the safety arrangement serves to completely fill the vessel with liquid in the event of fire in order to prevent inadmissibly high heating of the tank walls in the upper tank area which are not wetted and thus prevent bursting of the tank vessel possibly below the admissible operating pressure. <IMAGE>

Title: Electrical switching cabinet
Inventor: KOCH KURT
IPC: H02B1/14
Filed: 1985-03-05
Abstract: An electrical switching cabinet is disclosed having a flap which blocks or releases access to fuses as a function of the position of a switching lever. The flap has allocated to it a locking device which comprises the switching lever, a two-armed locking lever, an intermediate element which is connected thereto and a blocking element, as well as an angled lever which is connected to the flap and on which the blocking element is articulated. The flap can be locked by means of one arm of the locking lever. The second arm of the locking lever is blocked by the switching lever against unlocking of the flap until the switching lever is pivoted from an ON position via a centre-O position to an Earth position. The locking lever can be pivoted in a blocking manner over the switching lever as soon as the latter is in the Earth position. A thrusting movement of the blocking element is prevented by the intermediate element until the locking lever covers the switching lever. While the flap is pivoted, and in its open position, the intermediate element is blocked against displacement by the blocking element. <IMAGE>

Patent DE-3530332-A1 (DE)
Title: Pulsed bioreactor containing sponge elements for the immobilization of microorganisms or enzymes
Inventor: BRAUER HEINZ PROF DR ING
IPC: C12M1/40
Filed: 1985-08-24
Abstract: The invention relates to a bioreactor having a very high microbial or enzymatic substance conversion per unit of its volume. For this purpose, the bioreactor is packed with porous, sponge-like elements on whose surface the microorganisms or enzymes are immobilized. To ensure a uniform flow through the bioreactor and distribution of the organisms to guarantee a maximum space/time yield, the bioreactor is pulsed at specific time intervals; at the same time, a non-stationary time-limited backflow is superimposed on the stationary flow. The pulsed bioreactor is suitable for all those biological substance conversions in which only a very small growth rate of the biomass is present. This is particularly the case during anaerobic waste water purification with biogas production and during nitrification. The pulsed bioreactor according to the invention according to Figure 1 consists essentially of a cylindrical vessel 1 having one or more sponge elements 2 arranged on top of one another. According to the example selected, these are firmly connected to the vessel wall by means of a support ring 3. A further connection exists with the lifting rod arranged in the longitudinal axis. If this carries out a lifting motion at specific time intervals, the sponge elements are compressed and corresponding flows are forced in them which contribute decisively to the improvement of the biological substance conversion.
